X=bt + ct3, b=1.50m/s, c=0.640m/s3.
Average velocity = distance / time
ti = 1.00, tf = 3.00
xi = (1.50)(1.00) + (0.640 )(1.00)^3 = 1.5 + 0.640 = 2.14 m
xf = = (1.50)(3.00) + (0.640)(3.00)^3 = 4.5 + 27(17.28) = 21.78 m
Ave Velocity = (21.78 - 2.14) / (3 - 1) = 9.82 m/s
Answer:
Explanation:
given,
mass of the cart 1, m₁ = 310 g
speed of car 1 , v₁ = 1.25 m/s
mass of cart 2, m₂ = 260 g
speed of cart 2, v₂ = -1.33 m/s
speed of center of mass
Hence, speed of center of mass of the system is equal to 0.0732 m/s
Answer:
Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A
Explanation:
Let the depth of each section is h.
That means the real depth for each section is h.
Apparent depth is liquid A is 7 cm.
Apparent depth in liquid B is 6 cm.
Apparent depth in liquid C is 5 cm.
by the formula of the refractive index
n = real depth / apparent depth
where, n is the refractive index of the liquid.
For liquid A:
.... (1)
For liquid B:
..... (2)
For liquid C:
..... (3)
By comparing all the three equations
nc > nB > nA
Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A
Answer : I hope this helps !
The Effort Force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.
The answer is referred pain.
Referred pain is the slow pain that is origination from an internal organ is often perceived as coming from an area of the body totally unrelated to the source.
Pain is distressing feeling. When any stimuli damages, we feel a pain such as when finger burns or toe is stabbed etc.
